Referring now particularly to Fig. 1, 15 represents generally a standardtypewriter having supporting rear and front feet 16 and 17. The paper onwhich the typing operation is to be performed is carried on its Workroller 18. According to the present invention, the line copyhc-ldercomprises generally a feed roller mechanism 19 which is mounted abovethe top front portion of the typewriter in front of the work roller 18and supported by upstanding bracket members 20 and 21 that are connectedto angle shaped base members 22 and 23 respectively that are held inplace under the typewriter by the front feet 17 and further adjustablemembers 24 and 25 that are respectively connected to the members 22 and23 and which extend forwardly to the front lower edge of the typewriterand a manual actuator 26 connected to the forward ends of the adjustablemembers 24 and 25. To operate the roller mechanism a press button 27ofthe actuator 26 is depressed so that a flexible Wire 50 is extendedthrough a flexible conduit 28 that leads from the actuator 26 totheroller mechanism 19 to effect movement of a ratchet device 29 of theroller mechanism 19 and cause the step-by-step rotation of the rollermechanism and of the paper copy which the operator of members 32 and 33.Two rollers 34 and 35 laterally spaced from one another are iournalledin the end members 32 and 33.

3 These rollers have hand knobs 36 and 37 on their ends so that the userof the line copyholder can advance the paper by hand or can use the handknobs to adjust the rollers for effecting the connection of the ends ofthe paper upon the roller mechanism.

Laterally or horizontally spaced from the end members 32 and 33 and fromone another are two paper retaining members 38 and 39. Thesernembers, asshown in Fig. 3, are formed of spring strap and are secured to thebottom pan 31 by rivets 4-0. The end of each spring strap is rolledupwardly and bent upon itself to provide a paper retaining and guideportion 41 that partially surrounds the roller and which carries a smallengaging roller 42 that bears against the surface of the adjustableroller to catch and retain the ends of a paper sheet 43 as illustratedin Fig. 3 and to cause the roller to take the paper sheet into theroller mechanism.

Mounted in the end member 33 is the rack device or mechanism 29, Fig. 2.The end member 33 carries on its inner side a guide bracket 45 that issecured by a rivet 46 to the end member 33, Figs. 2 and 6. This bracketsupports and guides a rack 47 that has teeth 47' which engages withteeth 48 on drive roller 35. The rack 37 has an upstanding arm 49 towhich flexible wire 50 extending through conduit 28 is secured by a setscrew 51. The conduit 28 is secured to a post 52 on the end member 33 bya set screw 53. As the wire 50 is extended from the conduit 28, the rack47 is advanced and the roller 34 is turned through the connection of therack teeth 47' with the teeth 48 on the roller 35. A return spring 54 isconnected between the rack 47 and anchor bracket 55 on the bottom pan31, as shown in Fig. 2. The rack teeth 48 are connected to a hub portion56 that is secured to the roller 35 by a set screw 57 and in particularto its rod 35, Fig. 5.

The upper part of the end member 33 has an elongated slot 33' in whichthe upwardly extending arm 49 of the rack 47 may operate or travel,Figs. 1 and 5.

Pivoted upon the rod 35' of the roller 35 adjacent respectively to theend members 32 and 33 are representa tive pivot arms 59, only one beingshown, Fig. 1. Journalled and pivotally connected to the outer ends ofthe arms 59 are pivot brackets 61 secured by a pivot pin 62 and a cotter63 that carry a transparent line guide bar 64 that will run under thelines as they are copied. The guide bar 64 and the arms 59 can be liftedback toward the typewriter work roll 18 at times when the paper 43 isbeing secured to the roller mechanism 19. When in use, the bar isdropped down upon the roller 34.

Illustration is made of the movement of the transverse guide bar 64 inFig. 4 to show that it can be moved to different dotted line positions.

On the underface of the bottom pan 31 is a guide member 65 that receivesa supporting bar 66 which is longer than the pan and which has its endsextending outwardly from the respective end members 32 and 33 of theroller mechanism, and to which hinge members 67 and 68 are hingeablyconnected respectively thereto. These hinge members depend downwardlyalong the side of the typewriter, and to them there are connected byfastening bolt means 69 and 70 respectively upstanding bracket members20 and 21.

Each angle base member 22 and 23 is located under the front feet 17 ofthe typewriter. These angle base members 22 and 2.3 respectively haveupturned portions 71 and 72 by which the respective bracket members 20and 21 are connected to the base members in an adjustable manner by theprovision of elongated slots 73 and 74' in the respective members 20 and21 through which respective bolt fastening means 75 and 76 extend. Twotransversely extending portions 22' and 23' of the respective anglesupport members 22 and 23 are respectively connected to the swingablearms 24 and 25 in an adjustable manner by the provision of elongatedslots 4 77 and 78 in the respective arms 24 and 25 and fastening boltmeans 79 and 80.

On the underside of the manual actuator 26 are swivel guides 81 and 82which respectively receive the forward ends of the members 24 and 25.The actuator can accordingly be positioned at the center of the forwardedge of the typewriter and held rigid by the tightening of the members24 and 25 on their respective base members 22 and 23.

When the copyholder is placed on the table to the i right or to the leftof the typewriter and stood up independently thereof, the actuator 26may be fixed to the front of the typewriter by any suitable connectingmeans.

The actuator 26 comprises a casing 84 having a top portion 35 from whichthe press button 27 extends. The press button 27 has a vertical rack rod86 that is supported in a guide bracket 87 attached to the casing 84 byscrews 88, Figs. 7 and 8. This vertical rack rod 86 operates upon gear89 to turn its shaft 90 and a large gear 91 thereon that meshes with ahorizontally extending rack rod 92 that is slidable in a supportingbracket 93 and to one end of which there is fixed the end of the wire 50by means of a set screw 94. The brackets 87 and 93 are respectivelysupported upon a transversely extending partition 95 in the casing 84.The bracket 93 is fixed to the side of the partition by screws 93'.

The conduit 28 through which the wire 50 slides is fixed within thecasing 84 by a set screw 95 in a block 96 that is fixed to the innerside of the casing 84 by fastening screws 97 and 98, Fig. 8.

In order to alter the length of stroke of the press button 27 and theamount of movement of paper through the roller mechanism, there isprovided an adjustable shaft 100 that is journalled in the ends of thecasing 84 and can be turned by knobs 101 and 102 at the opposite ends ofthe actuator. This rod has opposite threads 103 and 104 andrepresentatively adjustable upon these threads are blocks 105 and 106 towhich links 107 and 108 are respectively connected. Surrounding the rackrod 86 and connected to the links of the links 107 and 108 is a stopmember 109 which can be adjusted up or down to provide a stop againstwhich the press button 27 will engage and to limit the length of strokeor downward movement of the press button whereby to alter the amount ofmovement of the paper in the roller mechanism. The links 107 and 108 arerespectively pivotally connected to the ends of the stop member 109 topermit this adjustment thereof.

Referring now particularly to Figs. 9 and 10, there is shown a modifiedform of roller to be used in the roller mechanism and more particularlyto the means for retaining the ends of the paper copy. A roller 111would be provided with a central pivot shaft 112. The roller ispreferably formed of rubber but is cut away at two 10- cations toprovide a recess 113 for receiving a spring strip 114 of arcuate shapeand which is fixed in the recess by fastening screws 115 that extendinto the roller 111. To the free end of the arcuate spring members 114is fixed by rivets 117 and inverted curved finger plate 116 of metal orplastic. The finger plate 116 can be elevated and the edge of the papersheet 43 can be inserted thereunder in the manner as illustrated in Fig.10.

The finger plate 116 extends substantially the entire length of theroller 111 and at the opposite ends of the roller are push buttonmembers 118 that extend diametrically through the roller for engagementwith the underside of the member 116 so that the member 116 can beelevated by pressing the push button members 118. Each of the bushbutton members 118 lies in a recess 119 and has a reduced diameter rodor shank portion 120 that engages the underface of the retaining member116. The push button 118 is held in place by an arcuate retaining plate121 that is fixed to the roller by fastening screws It will thu be seenby pressing the push button 118, the member 116 is released and thepaper edge can be inserted under the retaining member 116.

In Figs. 11, 12 and 13, there is shown a still further form of a rollerused with the paper copy roller mecha nism. This roller is indicatedgenerally at 125 and has a rod 126 extending therethrough. This roller125 has two parallel recesses 127 and 128 extending throughout thelength thereof and separated by a partition 129. Bal anced on the top ofthe partition 129 and secured thereto in a loose manner by a screw 130is a clamp plate 131 having an enlarged hole 132 for the screw 130 toprovide a sloppy or loose connection so as to allow pivotal movement ofthe plate 130 over the partition 129. One per tic-n of the plate 131dips into recess 127 as indicated at 133 to engage and secure the end ofpaper sheet 43 against one side of the recess 127.

The clamp plate 131. has projections 134 struck downwardly therefrom toextend into recess 128 and to engage a flat spring 135 secured acrossthe bottom of the recess 128 by fasteiing screws 138, Fig. 13. The plate131 is pressed into recess 128 so as to raise the clamping end 133 topermit the paper sheet 43 to be inserted thereunder and the fingerprojection 134 will engage spring 135 and will return the plate 131 sothat its end 133 will clamp the paper sheet 43 in the recess 127 In casethe copyholder is built into the typewriter, the actuator button can bein the form of a key and included in the keyboard of the typewriter andmade to be actuated within minimum force and movement, the same as thatof any other key and adapted to modern touch typing and whereby thefingers can be kept in the home position. The actuator can be operatedwith the thumb in the same manner that the space bar is operated.

Referring now particularly to Figs. 14 and 15, there is shown the formof the invention wherein the line-by-line copy holder 140 with its pressbutton actuator 141 built into and assembled within the typewriter shellbody 142. The typewriter shell is provided with a lift cover 143 thatcan be lifted or removed from the front of the type writer body toprovide access to the line copyholder 140 mounted within the typewriter.The line copyholder 140 has two rollers 144 and 145 which are journalledin an 7 end member 146 at one end of the copyholder 140 and in theratchet device at the opposite end of the copyholder. The ratchet deviceis connected by a fiexible wire 148 that extends through a conduit 149to the press button actuator 141 that has a press button 150 disposed between typewriter space bar members 151 and 152 that are coaxiallyaligned therewith. Roller turning and paper releasing knobs 153 and 154are provided on each side of the typewriter so that the paper sheet canbe rolled upon the rollers 144 and 145 or the rollers released to freethe paper sheet or permit the insertion thereof in a manner to behereinafter described. The actuator 141 has a rod 155 and turn knobsthat extend therethrough and through the opposite sides of thetypewriter body 142 and which can be turned to adjust the amount ofspacing that is to be effected by the press button 150 in the mannerabove described in connection with the actuator 26. The line copyholderwith the cover 143 of the typewriter removed is in a similar location tothe location of the line copyholder above described and in front of thetypewriter platen roller 157 and ribbon 158 and operable over the paperguide 159 and paper hold down bar 165. The roller platen 157 is turnedby either one of their end knobs 161 or 162.

It should now be apparent that there has been provided a line copyholderadapted for use with typewriters which can be installed at a locationabove the typewriter forwardly of the typewriter work roller or to theright or left thereof. It should also be apparent that the operatingparts of this mechanism can be embodied within the typewriter casingupon space being provided therefor. The actuator is located where it iseasily accessible and is ad- 63 justable to different lengths of strokeso that the operator of the typewriter can gauge the amount of movementof the paper by the roller mechanism.

It will be further seen that there is provided a mechanism that is easyto load with the paper sheet since the ends of the paper sheet areadequately and quickly secured to the rollers and the securement iseffected by simply using the pressing elements of the roller to admitthe end of the paper and wherein the rollers can be turned in a mannersimilar to the manner in which the work roller is turned on thetypewriter.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.
